Improving NWBC Quicklaunch Autofill

Hi All

We've got two questions about the NWBC autofill (start typing transaction name in the quick launch bar and you get a list of functions)

We are running NWBC4 PL12

1.  The autofill for Transactions and Applications is very useful but is case sensitive, i.e. if I am looking for ME21N Create Purchase Order, "create pur" will not find it but "Create Pur" will.  Is there any way to fix this?  If not, which is the lowest version of NWBC where this is fixed?  NWBC4 PL13 or PL14?

2. Can we control the transactions that appear in this search?  For example, there are two transactions Create Purchase Order - ME21 and ME21N.  We would prefer that only the latter appears because we don't use ME21.

Thanks

Chris
